More than 40 law enforcement, fire, search and rescue, and volunteer agencies -- including a Wake County Sheriff's Office K-9, the Fayetteville Police Department, and the Fayetteville and Cumberland County dive teams -- were helping in the search for Raul.

"I want to thank our partners and the community for the tremendous outpouring of support," Kersey said. "We greatly appreciate the thoughts and prayers for this little boy. Everyone has one goal to find Raul and bring him home safe."

On Friday, the North Carolina State Highway Patrol conducted a roadblock canvass in the neighborhood to talk to drivers.

Authorities asked that anyone who lives or works near the area and has surveillance cameras to please check them to see if there is anything unusual that you should share with law enforcement.

On Thursday, the Scotland County sheriff said the search shifted from a search or recovery to an "investigative side."

"We're in the process of setting up all that we need at different locations so that we can work this from an investigative side," Kersey said.

Authorities are still unsure whether the boy was abducted or if he wandered away.

Raul is described as Native American and Hispanic, approximately 3 feet tall, weighing 38 pounds. He has black hair and brown eyes.

He was last seen wearing a white-and-orange tiger-striped shirt with tigers on it and white pants with rocket ships printed on them.
